<P>PROBLEM TO BE SOLVED: To provide a nozzle to coat a water-stop agent in which dripping-off of the low viscosity water-stop agent can be prevented, and permeability can be elevated so that water-stop performance can be improved. <P>SOLUTION: A low viscosity silicone ejection port is opened at the widthwise direction center part of one face side of a rectangular shaped housing, and a high viscous silicone ejection port is installed on the lower side than the low viscous silicone ejection port, and the high viscous silicone ejection port is made to have a lengthy width extended from the low viscous silicone ejection port to both sides in the widthwise direction, and moreover, the supply passage communicating the high viscous silicone ejection port with the high viscous silicone supply port is arranged to have decreasing cross-sectional area toward the ejection port side, while the area of the high viscous silicone ejection port is arranged to be smaller than the area of the high viscous silicone supply port. <P>COPYRIGHT: (C)2008,JPO&INPIT |
